|Geochemical Creation of Methane - NASA/Goddard Space Flight Center|
Note: Conceptual animation depicting how geochemical processes during the course of Mars' history may have produced the methane plumes now seen in Mars' atmosphere. Here, through a process called serpentinization, methane is generated as part of a reaction involving the conversion of liquid water (seen seeping into the planet's crust), iron oxide, and carbon dioxide energized by the planet's internal heat into serpentine minerals...

|Biological Creation of Methane - NASA/Goddard Space Flight Center|
Note: Conceptual animation depicting how biological organisms (shown as oval-shaped translucent structures) living beneath the surface of Mars may have produced methane (shown as blue spheres). Animator: Susan Twardy (HTSI). Producer: Chris Smith (UMBC). Scientist: Michael Mumma (NASA/GSFC).

|Mars Methane Spectroscopy - NASA/Goddard Space Flight Center|
Note: Conceptual animation demonstrating the process of spectroscopy. The first animation demonstrates the general concept of visible-light spectroscopy by which white light is separated into its component wavelengths (colors) using a prism. The second animation demonstrates how this idea is applied to the discovery of methane in Mars' atmosphere. Because it absorbs specific wavelengths of electromagnetic energy, methane has a 'fingerprint' that can be seen as missing lines on the resulting spec...

|The Mystery of Martian Methane - NASA/Goddard Space Flight Center|
Note: Mike Mumma and his team of researchers at Goddard Space Flight Center have made the first definitive observations of methane in the atmosphere of Mars. The evidence of methane plumes only during certain seasons and the chemical processes that could lead to its possible sources both raise intriguing questions for future study.For complete transcript, click here.

|Sample Analysis at Mars (SAM) - NASA/Goddard Space Flight Center|
Sample Analysis at Mars (SAM) is a suite of instruments developed for use on the Mars Science Laboratory. By looking for evidence of water, carbon, and other important building blocks of life in the Mars soil and atmosphere, this suite will help answer one of humankind's biggest questions about the planet: did it ever support life? SAM was designed and built in an international collaboration between Goddard Space Flight Center, the Jet Propulsion Laboratory, the University of Paris, and Honeybee...

|Earth Day with Kenji Williams - NASA/Goddard Space Flight Center|
The DLN teamed with director and violinist Kenji Williams to present an out of this world experience known as Bella Gaia (Beautiful Earth). This one-of-a-kind multimedia journey of Earth, as observed from space, combined his music with NASA imagery. Bella Gaia was presented to students and teachers around the world during two webcasts from the Goddard studio. Note: A brief recap of the Earth Day DLN event, featuring Valerie Casasanto, Marci Delaney, and Kenji Williams.For complete transcript, cl...

|Star Trackers Light the Way - NASA/Goddard Space Flight Center|
Note: The Autonomous Star Trackers provide attitude data and motion rate of the satellite. They are based on a radiation hardened design and proprietary algorithms that ensure accurate and robust 3-axes attitude determination. These same instruments most recently flew onboard NASA's Messenger and Mars Reconnaissance Orbiter missions. For complete transcript, click here. Editor: Erica Drezek (HTSI)...

|LRO's Team Spirit with Joanne Baker - NASA/Goddard Space Flight Center Scientific Visualization Studio|
Note: The Lunar Reconnaissance Orbiter (LRO) is the first step to future missions to the Moon, Mars, and beyond. But a lot has to happen before we get there and one woman on the LRO team played a key role in 'putting it together.' Animator: Chris Meaney (HTSI). Editor: Erica Drezek (HTSI).

|Up to the Challenge - NASA/Goddard Space Flight Center|
Note: In October 2008, Goddard hosted The Discovery Channel's 'Young Scientist Challenge.' The challenge brought ten middle school student finalists from across the country to vie for the title of 'America's Top Young Scientist' and a chance to win a U.S. Savings Bond. Five teacher finalists contended for recognition as 'America's Top Science Teacher.' NASA scientists and educators helped design the activities, which both tested the communication skills of the students and celebrated 50 years of...
